Studies were made on the effect of the temperature in the conditioning chamber and the time of its action on the properties of OSB/4 glued in the inner layer with PMDI resin. The testing results showed that boards used for the purpose of the study were characterized by very good strength properties, and their values considerably exceed the requirements of the standard specification. Both the long-term action of air with increased (+60°C) and lowered (–20°C) temperature resulted in a decrease in their properties. Nevertheless, even after 12 weeks seasoning the studied boards complied with the requirements of the EN 300 standard.
